.To, dllwwhofir it concern:

- StateofiIowa, have. invented certain Improvements in Machines forSecuring Spokes in WheeLHubs, of 'which the following is as'pecification'.

. There is now known-in the art a class of metal wheels in which thespokes are secured by inserting theiri-nner ends through mortises intothe central opening of ahlib, and then upsetting them to head theirinner ends and also -form' collars or enlargements at the outersurfaceof the hub. I v v My machine is intended to perform thisupsetting operation rapidly and with. uniform results. v

In the'accompanying drawings, Figure 1 is a side elevation of themachine with aportion 'of the main gearwheel atdnesser-nnvmg rod-brokenawayto expose other parts to view. Fig. 2 is a top plan view of thesame. Fig. 3

- is an elevation of the spoke-clamping devices.

The machine embraces as its principal parts a device to sustain andadjust the hub, avibratory header acting within the hub t0 encured to aslide, B, mounted on a 'guid'efB. Theslide is sustained by alifting-spring, 13,-

A sliding The jawH is jointed at its lower \Vhen the rod Kmovesrearward,it causes the pitman to approximate a position at right anglesthereto, and in so doing to close the clamp. The rearward movement ofthe rod to close the aws is initiated by an angular footlever, K,pivoted to the frame and jointed to the collar which carries the pitman,as shown in Fig. 3. The action is completed, however, and the jawsforcibly closed by a cam-wheel, L, fixed on the main shaft and actingon-a roller in the end of rod K. Apin, K, on the rod K enters an openingin the rear end ofa lever, K pivoted on the frame and connected with thedriving-clutch D to throw the same out of action. The opening has itsforward side oblique to' the axis of the rod K, so that when the rod ismoved by the foot-lever to close the spokeclamp the pin actuates thele-' ver and engages the clutch, thus bringing into act-ion the cam tohold the clamp and also the eccentric to operate the header. The openingis of such size as to allow considerableplay of the pin therein and atthe rear side its edge is inclined laterally that .it may actuate thelever and disengage the clutch at the proper time.

The action ofthe machine is as follows: The clutch being disengaged, theclamp open, and the hub-support and heading-tool retracted, the hub isseated in an upright position in the support B. A spoke is then insertedat one end through the hole or mortise in the hub until its extremityextends into the central opening. The foot-lever B is then actuated tolower the support and the hub until the spoke enters the clamp outsideof the hub and presents its inner end opposite the header 0,

as shown in Fig. 7. The foot-lever K is then actuated,-closing the clampand bringing into play the clamp-confining cam and the header operatingeccentric. While the clamp holdsthe spoke immovabl y in place, theheader advances, first upsetting and enlarging the end within the huband then carrying the hub forward toward the outer end of the spoke, sothat the metal is upset and enlarged between the outer surface of thehub and the inner face of the clamp, as shown in Fig. 8. At thecompletion of the operation the header is retracted by the eccentric;but before it moves any considerable distance the cam, which is made ofirregular form, releases the rod K and permits the spring to open theclamp,thus releasing the spoke, so that the header may not, when usedin'a hub with a small axle-hole, pull the hub from the end of the spoke.At the proper time the camvallows the rod to retreat until its pinthrows the driving-clutch out of action.

When the machine is required to operate on very heavy spokes, Irecommend the adoption of devices such as shown in Figs. 4, 5, and 6 tooperate the heading-tool, as they are better adapted than those beforedescribed to withstand heavy strains. In Fig. 4 the cccentrio-rod isconnected to one end of a lever, M,

middle, connected at its upper end to the 00- centric-rod, and connectedat its lower end by an adjust-able pivot'to the rod which operates theheader-arm. In this instance the header carrying arm is fulcrumed nearthe headingtool.

In Fig.6 the lever M is fulerumed, as inthe previous example, near theheading-tool, and is jointed at its lower end adjustably to theeccentriorod. In each case the header-arm is slotted to admit of theoperating-arm being adjusted, in order to change the length of movementof the heading-tool. NVhcn operating on iron of large diameter, the toolrequires a longer movement than when operating on smaller metal.

Having thus described my invention, what I claim is- 1. In aspoke-fastening machine, a spokeholding clamp, in combination with thepivoted header-carrying arm, the eccentric, the rod connecting theeccentric and arm, and the yielding hub-support.

2. In a spoke-fastening mechanism, the pivoted arm providedrwith aheading-tool to enter a hub, in combination with an eccentric and aconnecting-rod mounted at one end around the eccentric and pivoted atthe other end to the header-carrying arm, as shown.

3. In a spoke-fastening machine, in combibination with a heading-tool toenter the hub,

the hub-sustaining device, in combination with a supporting spring and adepressinglever.

4. In combination with the vibratory headingtool, the hub'support, thevertically-sliding head having a horizontal sliding connection with thesupport, the spring to retract the support, the spring to lift the head,and the lever to depress the same.

5. In combination with the connected clamp- I to levers, theiroperatingpitman, the reciprocating rod connected to the latter, itsactuating.- cam, and the retracting-spring.

6. In a spokefastening machine, the clamping-levers, theiractuating-pitman, the reciprocating rod, the lever for starting saidrod, its actuating-cam, the cam-driving clutch, and theelutchcontrol1ing lever operated by the rod, as shown, whereby theinitial closing .of the jaws is caused to set the cam in motion.
